Key Features
- Dual 4-input NAND gate with two independent logic functions, enabling complex combinational logic decisions with four inputs each in a single 14-pin PDIP package
- High-speed CMOS (HC) family operates from 2V to 6V supply, offering wide voltage compatibility with both 3.3V and 5V logic systems with fast propagation speeds
- Through-hole PDIP package with industry-standard 74HC20 pinout ensures breadboard compatibility and direct replacement for legacy CMOS and TTL-equivalent designs
Applications
The CD74HC20E is used in digital logic systems requiring multi-input NAND operations, such as enable gating, chip select decoding, and interrupt logic in microcontroller and FPGA designs. Its dual 4-input configuration is particularly useful for implementing wide AND-invert functions that would otherwise require cascading multiple 2-input gates. Through-hole PDIP packaging makes it popular for educational electronics, prototyping, and field replacement in legacy equipment.

Frequently Asked Questions
What is the input configuration of the CD74HC20E?
The CD74HC20E contains two independent 4-input NAND gates, where each gate accepts four independent logic inputs and produces a single NAND output. All four inputs must be logic high simultaneously for the output to go low, providing a wide fan-in logic function in a single 14-pin package.
What supply voltage range does the CD74HC20E support?
The CD74HC20E operates from a supply voltage of 2V to 6V, covering both 3.3V and 5V logic systems. This wide range makes it compatible with modern low-voltage CMOS microcontrollers as well as legacy 5V TTL-level systems, without requiring additional level translation circuitry.
What package does the CD74HC20E use and is it breadboard-compatible?
The CD74HC20E uses a 14-pin PDIP (Plastic Dual Inline Package, JESD-30 code R-PDIP-T14) with standard 2.54mm lead pitch. This through-hole package is fully compatible with solderless breadboards and standard perforated prototyping boards, making it convenient for lab experiments and development work.
How does the CD74HC20E compare to the TTL 74LS20 or 74S20?
The CD74HC20E is a CMOS-technology replacement that offers several advantages over bipolar TTL variants like the 74LS20: it consumes far less quiescent power, supports a wider supply voltage range (2V to 6V vs. 4.75V to 5.25V), and has higher noise immunity. It is pin-compatible with 74LS20 in 5V systems.
Is the CD74HC20E RoHS compliant?
Yes, the CD74HC20E is RoHS compliant and lead-free, as indicated by its Pb-free code and JESD-609 code e4. It meets current environmental regulations for use in consumer electronics, industrial equipment, and other applications requiring restriction of hazardous substances compliance.
